Back around Y2K, I was attending & volunteering at the PVGP, many hot sounding inline 6's there. A Gentleman got 'hold of a vintage late '70's BMW IMSA class racer, 1st time out missin' gears, & sounded like fuel starvation issues...just a mess strugglin' to make a lap. The next year, BAM! Got it together, don't think l've heard a louder, haulin' *** straight six as it cranked out the stretch & the Panther Hollow bridge. That vid brings back the memory, wind baby wind!
